I Application filed June 12,1906. serial No. 321,369.

To all whom it mayc0acern.'

Be it known that I, LEWIS C. WETZEL, a

citizen of the United States, residing at Toledo, county of Lucas, an State of Ohio, have invented certain new a d useful Improvements in VVeighing-Scales, ofwhich the following is a specification.

The present invention relates more particularly to devices for securing the proper adjustment of the base upon which the novel features'in construction and combina tion of parts the essential elements of which are recited in the appended claims nd a preferred form of embodiment of whlch is described in detail hereinafter and fully illustrated in the accompanying drawings.

Figure 1 represents in front elevation computing weighing scales of a familiar type with the present invention embodied therein; Fig. 2 represents alportion of the base structure of such scales With a part broken out to disclose the interior construction; Fig. 3 represents this portion of thescales in longitudinal section, and Fig. 4

represents the same incross section.

By preference the type of weighing scales to which the *invention is shown'applied in the present c ase is'that disclosed in De Vilbiss Re-issue Patent No. 12,138, dated July 28, 1903, it being understood, however, that the invention is capable of application to and use with other types. For an under-- standing of the De Vilbiss computing weighing scales reference may be had to said re-issue patent and it will not be necessary to describe herein the details thereof.

It is customary in the manufacture of such scales to erect the weighing device upon ahollow base 1 which, in turn, rests upon a sub-base 2. By relative movement between these two parts of the base structure the proper level is attained for the weighing devices. It is usual for means to be employed whereby the base 1 may be pose. By the present invention it is proposed to improve the character of means for performing this operation. To this end the sub-base 2 is formed with upstanding internal lugs 3 spaced apart transversely of said sub-base. The base 1 is formed with bearings 1 on its inner sides which receive the bearings by caps 6 secured in place by screws 7. This rock shaft is formed with projecting arms 8 extendin over the lugs 3 respectively, the latter being preferably brought have a rocking bearing thereon. Another arm-9 projects in the opposite direction from said rock shaft and is formed with an orificc at 10 through which extends loosely a vertical bolt 11. The latter is threaded at its lower end andcarries a nut 12 which occupies a recess 13 in the arm 9 under the orificed portion thereof. The upper wall of the recess has a conical formation, as shown at 14, so as to provide a rocking bearing \ries/above the same a finger piece in the form of a thumb nut 15. The character of the adjusting means described provides for this thumb nut standing immediately in it can be readily manipulated.

The turning of the thumb nut15 in one direction will cause the nut 12 to rock the arm 14 and consequently press the arms 8 upon the lugs'3. In this manner the base 1 may be elevated at the end where the ad justing devices are located. The turning of of course permit-this part of the base to lower. It will be seen therefore, that the devices described provide adjusting'means whereby the base may be brought to the proper level. It will be noted that by providing the transversely spaced lugs on the sub-base and the transversely extending rock shaft with its correspondingly s aced arms engaging said lugs, any lateral tilting or rocking of the basel is prohibited.

Thus it will be seen that the objects primarily stated are effectively accomplished by the above described means. However, it

18 to be-understood that the form of embodito rounding edges so that said arms 8 may raised or lowered at one end for this purjournals of a rock shaft 5 confined in said for said nut 12. The bolt 11 extends through an orifice in the top of the base 1 and carfront of the housing 16 of the scales where the thumb nut in the opposite direction will 1 ment of the invention may be more or less modified as compared with that here shown and described.

What is claimed is:

1. The combination with base and subbase, of means for relatively adjusting the same for the purpose of leveling the former, said means comprising a rocking member extending laterally of the base, abutmentsof the base for operating said rocking member.

3. The combination with base and subbase, of means for relatively adjusting the same to level the former, said means comprising transversely or laterally spaced lugs on the sub-base, a rock shaft journaled in the base and having arms engaging said lugs respectively and an operating arm, and a fingerpiece connected with the latter.

4. The combination with base and subbase, of means for relatively adjusting the same to level the former, said means comprising transversely or laterally spaced lugs on the sub-base, a' rock shaft journaled in the base and having arms engaging said lugs respectively and an operating arm, and -a finger piece connected with the latter and located at the front of the base.

5 The combination with base and subbase,.of means for relatively adjusting the 'same-to'level the former, said means comprising transversely or laterally spaced lugs on the sub-base, a rock shaft journaled in the base and having arms engaging said lugs respectively and an operating arm, and a bolt carrying a nut engaging the latter said bolt having a head outside the base.

6. The combination with base and subbase, of means for relatively adjusting the sameto level the former, said means comprising transversely or laterally spaced lugs on the sub-base, a rock shaft journaled in the base and having arms engaging said lugs respectively and an operating arm, and a bolt carrying a nut engaging the latter and having ahead outside the base at the front part threreof.

7. A leveling device for apparatus of the character described, the same comprising, in combination with the base a rock shaft journaled in the latter and having bearing arms laterally spaced apart relative to the base and means for adjusting said shaft.

8. A leveling device for apparatus of the A character described, the same comprising 1n combination with the base a rock shaft journaled in the latter and having bearing arms laterally spaced apart and adapted and arranged to engage a support, an operating arm, and adjusting devices applied thereto.

9. A leveling device for apparatus of the character described; the same comprising.

in combination with the base, a rock shaft journaled in the latter and having bearing arms laterally spaced apart relative to the base, and an operating arm; and anadjusting bolt and nut applied tosaid operating arm.

10. A leveling device for apparatus of the character described, the same comprising, in c ombination with the base, a rock shaft having a projecting arm for adjustably supporting the base, and means for adjusting the shaft. f

11. A leveling device for apparatus of the -character described, the same comprising,

in combination with the base, a rock shaft having aprojecting arm for adjustably sup porting the base, and also having an operating arm; and means applied to the latter for adjusting the shaft.

12. In apparatus of the character described, the combination of a hollow base, a rock shaft journaled therein and having a projecting arm for adjustably supporting the base; and a finger piece on the exterior of the base adapted to adjustsaid shaft.

13. In apparatus of the character' described, the combination of a hollow base, a'

rock shaft journaled therein and having a projecting arm for adjustably supporting the base, and also having an operatlng arm;

and a finger piece on the exterior of the base and connected with said operating arm to adjust the said shaft.

14. In apparatus of the character described, the combination of a hollow base, a rock shaft journaled therein and having a projecting arm for adjustably supporting the base,'and also having an orifice operating arm; a finger piece in the form of a bolt engaging the orifice of the operating arm and projecting to the exterior of the base; and a nut on said bolt engaging said operating arm.
